Journal ArticleDOI
Optical Anisotropy in Single Light-Emitting Polymer Nanofibers
Stefano Pagliara,M. S. Vitiello,Andrea Camposeo,Alessandro Polini,Roberto Cingolani,Gaetano Scamarcio,Dario Pisignano +6 more
TL;DR: In this article, the optical anisotropy of single nanofibers realized by electrospinning a conjugated polymer was investigated, showing that the fraction of ordered molecules is correlated to the fibers morphology.
Journal ArticleDOI
Temperature Dependence of Thermal Conductivity and Boundary Resistance in THz Quantum Cascade Lasers
TL;DR: In this article, the lattice temperature distribution, the cross-plane thermal conductivity and the thermal boundary resistance of the As quantum cascade lasers (QCLs) operating at 2.83 THz in the heat sink temperature range 45-300 K were measured from the analysis of microprobe band-to-band photoluminescence.
Journal ArticleDOI
THz QCL-based cryogen-free spectrometer for in situ trace gas sensing.
Luigi Consolino,Saverio Bartalini,Harvey E. Beere,David A. Ritchie,M. S. Vitiello,Paolo De Natale +5 more
TL;DR: It is shown that the sensitivity of methanol vapour detection can be improved by a factor ≈ 4 with respect to standard direct absorption approaches, offering perspectives for high sensitivity detection of a number of chemical compounds across the far-infrared spectral range.
Journal ArticleDOI
Thermal Modeling of Terahertz Quantum-Cascade Lasers: Comparison of Optical Waveguides
C. A. Evans,Dragan Indjin,Zoran Ikonic,Paul Harrison,M. S. Vitiello,Vincenzo Spagnolo,Gaetano Scamarcio +6 more
TL;DR: In this paper, a set of experimental lattice temperature profiles measured in a surface-emitting terahertz (THz) quantum-cascade laser (QCL) with the results of a 2-D anisotropic heat diffusion model is compared.
Journal ArticleDOI
Electron-lattice coupling in bound-to-continuum THz quantum-cascade lasers
M. S. Vitiello,Gaetano Scamarcio,Vincenzo Spagnolo,Tonia Losco,R. P. Green,Alessandro Tredicucci,Harvey E. Beere,David A. Ritchie +7 more
TL;DR: In this article, the authors measured the thermal resistance (R=20.1K∕W) and electrical power dependence of the electronic temperature (Re=27.0K ∼50 times lower than THz QCLs with resonant-phonon active region scheme in the lattice temperature range of 30-100K.
